Background and Aims: The internet and social media are increasingly accessible to people with intellectual disabilities, offering significant benefits but also posing unique challenges and risks. This study aimed to explore the online experiences of adults with intellectual disabilities in England. Methods: An accessible survey was conducted from July 2021 to July 2022 collecting data on online risks, perceived benefits and barriers to internet use. Results: Amongst 115 participants, 74% reported using the internet daily, and 48% used social media every day. Participants who reported more frequent engagement in cyber-aggression were significantly more likely to also report experiences of cyber-victimisation. Conclusions: The findings highlight the evolving use of the internet for adults with intellectual disabilities and the factors that influence their online experiences. They emphasise the need for strategies to enhance safe internet use and inform social care practices aimed at fostering positive online experiences whilst mitigating risks.
